Freeport Reports on PT Freeport Indonesia Operations

Audio By Carbonatix

PHOENIX--(BUSINESS WIRE)--Sep 9, 2025--

Freeport (NYSE: FCX) announced that on Monday, September 8 at approximately 10 p.m. local time in Central Papua, Indonesia, a large flow of wet material from a production drawpoint occurred at one of five production blocks in the Grasberg Block Cave underground mine. The incident blocked access to certain areas within the mine, restricting evacuation routes for seven team members.

The location of the workers is known, and they are believed to be safe. Crews are working to clear the area for a safe and expeditious evacuation. In parallel, activities are underway to provide support to the workers.

At the Grasberg Block Cave operation, ore is mined using remotely operated equipment; however, the material flow from this event blocked access routes where the affected team members were engaged in mine development activities. All other personnel are confirmed safe.

Mining operations in the Grasberg minerals district have been temporarily suspended to prioritize the safe evacuation of the seven contractor workers.

Richard C. Adkerson, Chairman of the Board, and Kathleen Quirk, President and Chief Executive Officer, said: “The safety and wellbeing of our workforce is always our number one priority. Our team is working diligently to bring our team members to safety as quickly as possible.”
